PROFILE
Ohad Revah
Orevah contributed to the RedHatQE/openshift-virtualization-tests repository by engineering robust observability and metrics validation for virtualization on Kubernetes. Over ten months, Orevah expanded cross-platform test coverage, especially for Windows and Linux VMs, and improved CI reliability by refactoring flaky tests and streamlining test utilities. Using Python, Pytest, and YAML, Orevah developed and stabilized metric tests for VM lifecycle, migration, and network monitoring, while enhancing dependency management and test automation. The work included custom CLI download validation and cross-network compatibility, resulting in more accurate telemetry, faster feedback cycles, and maintainable test infrastructure that supports safer, data-driven OpenShift virtualization releases.

Sep 1, 2025Month: 2025-09 — Delivered cross-platform stability and observability improvements for the RedHatQE/openshift-virtualization-tests project, with focused feature delivery and rigorous test hygiene. Key features delivered include (1) OpenShift Python wrapper upgrade to v11.0.91 with a Windows cross-platform compatibility adjustment to the click dependency marker (sys_platform == 'win32'), and (2) CNV metrics observability enhancements featuring workqueue metrics tests, flaky-test cleanup, and refactoring of network metric collection. Major bugs fixed and stability improvements include stabilization of the kubevirt_virt_operator_ready test and a targeted reduction of CI noise through removal of brittle tests (kube_daemonset_status_number_ready; tests with T1 cover; runbook URL tests; CDI metrics recording rules). Overall impact: faster feedback loops, higher confidence in CNV metrics, reduced runtime flakiness, and improved maintainability of the test suite. Technologies/skills demonstrated: Python packaging and dependency management, cross-platform compatibility engineering, observability instrumentation, test reliability engineering, and diligent test-suite cleanup for stable CI/CD pipelines.

Jun 1, 2025June 2025 focused on strengthening metrics reliability, expanding cross‑platform test coverage, and simplifying maintenance for the RedHatQE/openshift-virtualization-tests repository. Key feature work included building Windows VM metrics testing coverage with Windows-specific fixtures and tests for memory, network, and filesystem/disk usage, plus deployment streamlining and skip logic when Jira issues are open. A new CDI Import Pods High Restart metric test was added, including a metric constant, a fake DataVolume fixture, and validation of metric increments after DataVolume creation. Major bug fixes improved telemetry accuracy and test stability, notably correcting migration metrics increment logic and removing redundant metrics, and addressing flakiness in Memory/Network tests with fixture refactors and test quarantines for known CNV-64128 issues. An ARM64 test suite simplification was implemented to reduce maintenance overhead by removing an open-Jira check in the ARM64 VM architecture configuration test. Overall, these efforts deliver more trustworthy metrics, faster CI feedback, and broader cross‑platform validation, enabling safer releases and data-driven improvements across platforms.
